I need some advice on my salt water generator. It has a T 15 cell. I noticed the other day it was reading my salt levels low, so I added salt. Come to find out it was not accurate and I ended up with about 5000 ppm salt in my pool. That was my first mistake I should’ve tested my salt, but it was not surprising because we’ve had a ton of rain. Anyway I deluded it and got it back down to about 3600 ppm. I followed instructions and tried to re-calibrate my control module. But no matter what I do it always goes back to inspect cell, and reads a lower salt level again, this morning it was showing 2000. So I recalibrated it once again, and within 10 minutes it’s flashing low salt and inspect cell again. Also the reading has dropped down to 2500 ppm again. I have checked and cleaned the cell, probably twice a year, and again did it just the other day so it is clean. I normally soak it in 25% solution with my PH mutation acid. I think I know the answer, my cell is probably shot. I just want to make sure I’m not missing something. Of course even though it says generating on the readout, I have to add chlorine to maintain sanitation. If I do need a new cell, where would you recommend I purchase it from? I see them online for about half price for some replacement cells, versus the expensive Hayward. If I’m remembering right this is only two years old. I’m hoping I don’t have to replace everything. Thanks in advance for any advice.
